Unsightly Under Coating

If your car has undercoating that is visable
and quite old and Nasty looking, here's what to do!

Use truck bed coating to give your fender wells a good clean look.



Here's the materials you'll need.
Dupli-Color Truck bed coating $7.97 per can

* Scraper
* Drill
* Wire wheel
* Respirator
* Rubber Gloves
* Masking tape/painters tape
* Old Newspaper
* Saftey Glasses(Very Important)
* Asprin

First, Get your car up on jack stands and remove wheel. Please use Saftey Glasses! Begin scraping off the undercoating. With your first few scrapes, you'll realize what your getting into. This part is very teadious. But, the more undercoating you get off at this point, the better the results.



I know,your thinking why not use stripper? Very messy.
Here's a tip. Take your scraper over to the grinder and sharpen it up.



Continue scraping off undercoating. Try not to pry out factory seam sealing.
If you do, just re-seal before applying Bedliner Coating.






Once you have removed all of the undercoating, use a wire wheel and drill to remove undercoating left from scraping. Make sure you get into the nooks and crannies.



Next, Use painters/masking tape and old newspaper to Prevent overspray from getting on your paint/floor/frontend.



Now, Put on your respirator and rubber gloves and begin spraying on the bedliner coating. Note: Use light coats. This coating will build up to desired thickness. Again use light even coats with a few minutes between coats. Use in a ventilated area.






Finished surface is much more pleasant to look at yet just as protective, if not more so.



The before an after results are amazing!





You will be pleased with what you've done. It really makes a diffence! Compare both sides once you have completed one side. You won't believe how nasty it really did look!

Looks great! I have been using the same durable bed liner for several years.

Rick,
Nice work and great photos. You should send your story into that show "Dirty Jobs", looks like their hurting for fresh stories. Wear your FM T-shirt during the filming .

Rick, good right up. I have done that in the past and it is a messy job. For the really tough undercoating, a right angle grinder w/ a cup brush works amazingly well. I will say if you do use a cup brush, they tend to throw off those sharp metal wires as they get used up so it is good to wear long leather gloves, a sweathshirt and a face shield. But they make super quick work of any and all undercoating. -Mike

I have found that adding a little heat really helps this stuff come off.

I agree, a good heat gun is the ticket to easy removal. No grinder needed. I used Por15 afterwards, but bed liner is probably a 'better idea'. I believe I will try a couple of cans over the paint.

Wish I had a personal photographer. LOL

It seemed to get a little too gooey for me with heat. It did move easier with heat but, left too much goo for my taste. Not saying I tasted it! For the most part it did come up in pretty good chunks down to the metal. It's my wife Melissa (Mel's) car. I did did let her scrape until her palm was sore, then she took pictures! hehe. It's awesome though. She loves jumping in there to get her hands dirty....Kinda turns me on! I'm a very lucky man, I know.

Can somebody please send me a woman like this!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

our 65 gal had about 1/8~3/8 inch of ziebart under it- was the absolute messiest job I ever did...I used the rt angle grinder and knotted cup brushes, filthy/noisy...I was also going to do the bedliner, but after cleaning it off and etching it with Ospho to prevent rust under the paint, and putting a coat of POR15 primer on it, kinda liked the light blue, so just blacked out areas you could see like wheelwells/trunk floor, left the rest light...really brightens it up when working underneath.

Hey Ford4v429

WOW! that's some info I needed ~ THANK YOU.

Here's what I'm going to do being that I'm new to all this great restoration stuff.

My '66 Ford Convert. front fender is off the car (plus lots of other parts)
And low and behold I took off some 10 to 15lbs. of heavy tar undercoating.

THANK GOD it come to me to use my Burzomatic torch and a stiff paint scraper. Other than the smell (i wore a face mask to cover my ugly face . . .lol )

Seriously, the tar-like undercoating came off rather easily.

I just order: POR-15 Silver. However THANKS 2 U I got all or most of the rust off the inner fender and I'm going to hit the area FIRST with: OSPHO than the POR-15

Tell me what you think ? I'm I on the right track ?
Thanks again 4 sharing your experience and strength.

GOD BLESS
